Having got them out and attempted a clean, there's still a fair bit of brake dust on them, especially on the insides - I'm sure someone more patient than me would get most of it off. No kerb marks so externally they look pretty good. The left rear does have some corrosion on the inside so may will need a refurb or touch up.

Corrosion on rear left:
Tyres are all Yoko A039's with 5mm tread. They are a fair age however - going by the date markings the rears are from '05 and the fronts '06 and '03. Right rear has also had a puncture repair at some point.
